Use the nap control below exercise, or use a Sleeping bag. The Basic Training course distinguishes sleep and energy recovery from the shorter-term stamina spent on physical actions.
Choose where you sleep
The surface matters: the tutorial describes rubber as comfortable and rock as harsh. A Sleeping bag improves sleeping quality by one tier, capped at Good, and adds insulation. Its description also says normal sleep restrictions still apply.
Do not assume carrying a bag grants unrestricted rest. Use it through its item interaction and check the current condition preventing sleep.
Why sleep is unavailable
Pain, sickness and insufficient tiredness can interact with sleep restrictions. The run-settings text exposes a No sleep restrictions option, while sleeping pills describe allowing sleep in bad physical condition. The same pill description warns against combining them with opioids.
These are in-game item interactions, not real-world advice or a recommended drug combination.
Multiplayer is a separate case
The co-op mod README lists sleeping as disabled, tied to its EnableSleep rule. If the issue exists only in a modded session, check that rule and the exact installed mod version instead of treating it as a vanilla bug. Continue with co-op rules or run settings.
